So I downloaded the Trial Version of Lightburn, mostly to see if it would be worth the money. So far I’m a bit underwhelmed.
There seems to be a few issues with how it implements Inline Mode for Marlin. As discussed in this thread, it fails to insert an M03 I command into the Gcode output. I had to manually insert the M03 I and M05 I commands into the user start and end codes to make the laser turn on. And there doesn’t seem to be any way (other than manually editing the Gcode or the user starting code) to implement M04 Dynamic Inline Mode.
The developer seems kind of hostile toward Marlin (based on comments in some posts in the LB Forum), and I’m not pumped about spending money on a product that doesn’t really work well for the equipment I use. It’s a shame, because LB seems to work really well for GRBL users,
Maybe I’ll end up buying it anyway, if I can figure out all the required work-arounds before the trial period expires. So far there doesn’t seem to be many alternatives out there that work in a Marlin environment. Laser GRBL has been suggested by some, but again, it doesn’t really work in a Marlin environment AFAICT.
